Traditional Liner Design Is Out Of Fashion

with the development of modern production, the increasing diameter ball mill

, mill about five meters in diameter has been widely applied in production, so lining and grinding balls of increasingly high quality requirements. Therefore, the study of new anti-wear material linings, grinding balls, create ball mill (ball mill) in top working condition is to increase production, reduce consumption, an important way to fight for good economic and civilized environment. Lining and grinding balls a long time in harsh conditions, the amount of maintenance and replacement are quite large, not only a waste of manpower, material and financial resources, and direct impact on production efficiency, the impact of the civilization of the modern enterprise producing traditional liner installation structure of the main There are two forms, one is widely used in thermal power plants "dovetail bite, tighten the wedge is fixed"; jaw crusher ore industry status quo, a mining, cement, chemicals, and domestic and foreign large-scale thermal power plant widely used in every block of the liner with the bolts, respectively fixed in the cylinder of the seventies and eighties, at home and abroad to launch a large number of high hardness liner, Grinding Ball, such as high chromium cast iron, Ni-hard cast iron, high carbon alloy steelmartensite ductile iron and carbon steel, but because of the toughness values of these materials are relatively low, some ak value of about only 5J.

Fundamental mistakes were made in the traditional liner design can not adapt to the development of anti-wear material by the shackles of traditional liner forms are not widely promote the use of liner fracture has become a high hardness, high wear material applications, the biggest obstacle to the former leakage powder and the root causes of broken bolts, while the latter showed that the anti-wear performance can not be imagined: one must note here is that even if part of the work hardening, nor as a sign of anti-wear degree of jaw crushers in ore the application status of the industry, because the hardening is a kind of "damage" after the hardening, the initial hardness of it and the lining is the difference between the traditional high-manganese steel is unfit for the ball mill liner, which is already well-known The disadvantage of high-manganese steel liner: prone to creep and extension of the surface phase transition caused by anti-bow deformation in the ball mill operating conditions can not be the ideal hardening.

With its high quality products such as Sand washer, Flotation machine, Vibratory feeder, Raymond mill, Ball mill, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
